Stillen Air to Air setup

Z&I

Found this on the 350z site:
This was posted regarding the physical characteristics of the different vortech SC'rs but doesn't include the actual performance specs.
You can go to the Vortech site for them.

V2 Si = std bearing 53rpm/more efficient cast impeller
V2 T = HD bearing 55krpm/cast impeller
V1 T = HD bearing but bigger straight cut gears so stronger but noisier than the V2 >V3

V3 SCi = V2 SCi = std bearing 53krpm/improved cast impellers rom sc

V2 Ti (new) = HD bearing 55rpm/ more efficient billet impeller
V1 Ti : as above

V7 YSi = HD race bearing 65krpm/ cast impeller
V7 YSi (new)= HD race bearing 65krpm/ billet impeller

The V2 as offers superior cooling but others prefer the simplicity of the self lubricated V3. But if you factor in the recommended sc oil changes it's not so simple or cheap.
